Other Markets Conductive inks and pastes are used in a variety of other applications including circuit boards, membrane switches, automotive, sen- sors, RFID antennas, etc. Here are just a few ap- plication examples of these sectors: Printed Circuit Boards: Silver paste is screen printed on printed circuit boards to fill in vias.

In the exterior, screen printed silver paste is used in window heaters, while in the interior seat sen- sors, seat heaters, airbag dispatchers, dashboard illumination, overhead consoles (in-mould electronics) are used.
